In the vast forests and treacherous wilderness, a handy outdoor knife and practical tools are crucial for explorers to deal with emergencies and maintain survival. Mastering the usage skills of these tools can enable you to overcome dangers and survive in extreme environments. Now, let's introduce the practical survival techniques of outdoor knives and other tools for you. 

I. Outdoor Knife: The All-Purpose Companion in the Wild 

(1) Key Points for Knife Selection 

When choosing an outdoor knife, consider the blade material, blade length, and structure. High-carbon steel or stainless steel is preferred for the blade as it has high hardness and sharpness, but be cautious about rust prevention; stainless steel has good rust resistance and is suitable for humid environments. The blade length is recommended to be between 15 - 30 centimeters. It is too long to carry and too short to handle heavy tasks. Straight knives are more reliable than folding knives as they are less likely to fail in critical moments due to complex structures. 

(2) Basic Usage Skills 

- Cutting and Deburring Wood: Secure the wood and use the weight of the knife and the strength of your arm to make a 45-degree angle cut on the wood. When deburring or making wooden sticks or wooden spoons, fix the knife and push the wood towards the blade to prevent hand injuries. 

- Handling Game and Food: The sharp tip of the knife can be used for fine cutting, such as removing animal bones and cleaning fish guts; the serrated edge on the back of the knife can quickly saw through thicker branches. 

- Emergency Defense: When threatened by wild animals, hold the knife in your hand, stay alert, and use the knife's deterrent effect to prevent the animals from approaching easily. 

(3) Maintenance and Care 

After each use, rinse the knife with clean water, dry it, and apply anti-rust oil. Store it in a dry sheath. Regularly use a sharpening stone for maintenance to keep the blade sharp and extend its lifespan. 

II. Other Essential Outdoor Tools and Usage Skills 

(1) Multi-Functional Bulldozer 

- Excavation Function: When building shelters, it can be used to dig foundations and drainage ditches; when searching for water sources, it can dig shallow wells. 

- Cutting Function: The sharp edge of the blade can cut thinner branches, and the serrated edge on the back can saw through thicker tree trunks. 

- Emergency Weapon: In case of danger, the bulldozer can be used as a self-defense weapon. Its weight and length can generate strong deterrence. 

(2) Fire Starter and Magnifying Glass 

- Fire Making with Fire Starter: Place dry flammable materials (such as birch bark, pine needles) on the ignition material and use the fire starter and knife to rub together to produce sparks, igniting the flammable material. 

- Fire Making with Magnifying Glass: In sunny conditions, use the magnifying glass to focus sunlight on the flammable material and wait for the temperature to rise before igniting. 

(3) Rope and Compass 

- Rope Usage: Use it to secure supports when building tents; make a simple stretcher to carry injured people; set traps to catch small game. Be careful not to over-tighten the rope. 

- Navigation with Compass: In the absence of GPS signals, use the compass to determine direction. Place it horizontally and keep it away from metal objects to avoid interference with the magnetic needle's orientation.
